Directions were very easy to follow, video was a great help. I'd also highly recommend you follow Evan's suggestion for getting a traveller's sim.
He's very accommodating - from helping with directions to and fro to concerns about the house (I unintentionally "decorated" the room, clumsy me!).
We were able to commute like locals through the MRT as it's really close to the station.
I would looovee to go back to BKK and stay in one of his places again. Oh, and he says 'hi' when you bump into him. Haha. Thanks for making our Bangkok trip so easy, Evan!
